It looks like an urchin!

Since I stocked a coral ring in the shop (the first one ever) I've been looking at other vintage coral pieces. And here is what I've learned: They are amazing. Why? Well, usually they are huge and creatively designed, particularly retro pieces. I am currently obsessed with this ring, which not only has coral but also emeralds, onyx and diamonds. It looks like the underbelly of a sea urchin to me.
